Huicholes: The Last Peyote Guardians, Hernan Vilchez' documentary about the Wixárika People and their struggle to preserve the sacred territory of Wirikuta - the destination of their annual peyote pilgrimage - is due for release April 2013 according to the Facebook page for the film. The plot outline reads:

Huicholes: The Last Peyote Guardians is a story about the mystical Wixárika People, one of the last pre-Hispanic alive cultures in Latin America, and their ongoing struggle against the mexican government and multinational mining corporations to preserve Wirikuta, their most sacred territory and home of the famous peyote cactus.

Since 2010, Canadian mining projects received the concessions to prospect the whole area, rich in silver and other valuable minerals. The company promises to create thousand of jobs for the needy villagers of the region, without contamination.

Nevertheless, the mining activities are seen by the Wixárika and their supporters as a great menace for the delicate biodiversity of this unique ecosystem, listed by the UNESCO as World Cultural and Natural Heritage.

An unequal and controversial fight from today that triggers the global debate between ancient cultural values, the exploitation of nature and the inevitable development of the peoples.

Shark finning refers to the removal and retention of shark fins and the discard at sea of the carcass. The shark is most often still alive when it is tossed back into the water. Unable to swim, the shark slowly sinks toward the bottom where it is eaten alive by other fish.

Shark specialists estimate that 100 million sharks are killed for their fins, annually.

The above quotes are taken from the website of Sharkwater, a documentary that was aired yesterday on Danish television. I sat down watching it not really knowing what to expect, but were soon shocked and outraged by what I saw.

Sharkwater is a documentary by the Canadian filmmaker Rob Stewart who is driven by a lifelong fascination with sharks.Stewart uses the first part of the documentary to debunk the reputation of sharks as bloodthirsty, man-eating monsters and documents how few fatal incidents sharks are actually involved in (or as Wikipedia puts it: "when the facts are examined it can be seen that a shark attack is one of the rarest ways for humans to die. On average, there are a minuscule 5 fatal shark attacks per year worldwide"). Stewart also argues how sharks as apex predators have had a vital influence on the evolution of the seas; sharks have been around for more than 400 million years, before the times of the dinosaurs. Then the documentary segue into a sinister account of how a horrendous number of sharks are killed each year, bringing many species to the brink of extinction. Only a minor part of the shark, the fins, is actually used, reminding me of the cruel mindless waste of the wholesale slaughter of the North American bison (nothing to do with Lophophora, I know, but I felt it important to help spreading the word about this disaster).

It seems like the movie (A whale shark had its fins cut off while still alive, then left to die) couldn't be embedded - you can watch it at http://www.youtube.com/watch?v=a2P90_bJ3wcA whale shark had its fins cut off while still alive, then left to die

Shark fin is a popular delicacy in Asia - especially China, where it is typically served in shark fin soup at weddings, business dinners, etc. Shark fins are big business, allegedly a bowl of shark fin soup can fetch up to $120! Consequently sharks are killed in the millions (as mentioned above some experts estimate 100 million sharks are killed each year), diminishing the populations alarmingly fast - some to the point of extinction. On top of that the sharks are killed in an extremely cruel way, the fins are usually sliced off as the shark is still alive and the finless body is dumped back into the ocean left to a slow death.

Concerned voices are also raised regarding how the ecosystems of the ocean will be affected by removing massive numbers of top-level predators. The IUCN Shark Specialist Group Finning Statement says: "shark finning [...] threatens many shark stocks, the stability of marine ecosystems, sustainable traditional fisheries, food security and socioeconomically important recreational fisheries" and concludes that "a ban on shark finning is justified throughout the world’s oceans and high seas".

Not to mention the tremendous waste: the IUCN Information Paper on Shark Finning states that "The most widely used fin:carcass ratio was developed by the US National Marine Fisheries Service (NMFS) in the early 1990s. NMFS adopted a ratio of 5% fin weight to 95% dressed (gutted and beheaded) carcass weight based on samples of sharks dressed at sea under commercial fishing conditions in the Northwest Atlantic, and using the ratio appropriate for species with the largest fins", meaning that less than 5% of the killed animal is actually used.

The screening of Sharkwater was followed by an analysis by a shark biologist from my old university. Asked if Sharkwater should be considered a sober or exaggerated "eco documentary" she replied that the situation as described by Rob Stewart is very much for real - millions of sharks are killed each year for their fins and many species will become extinct if action is not taken now!

It's sad to see how these magnificent creatures have gone from predator to prey, and how despite surviving the earth's history of mass extinctions, they could easily be wiped out within a few years due to human greed.

The History Channel has released its feature-length documentary Peyote to LSD: A Psychedelic Odyssey on DVD. The documentary is written by Peter von Puttkamer and botanist Wade Davis and follows Davis as he reconstructs the travels and discoveries of his renowned mentor and fellow botanist Richard Evans Schultes, the father of modern ethnobotany. Or as von Puttkamer puts it:

Plant Explorer Richard Evans Schultes was a real life Indiana Jones whose discoveries of hallucinogenic plants laid the foundation for the psychedelic sixties. Now in this two hour History Channel TV Special, his former student Wade Davis, follows in his footsteps to experience the discoveries that Schultes brought to the western world. Shot around the planet, from Canada to the Amazon, we experience rarely seen native hallucinogenic ceremonies and find out the true events leading up to the Psychedelic Sixties. Featuring author/adventurer Wade Davis (“Serpent and the Rainbow”), Dr. Andrew Weil, the Grateful Dead’s Bob Weir and many others, this program tells the story of the discovery of peyote, magic mushrooms and beyond: one man’s little known quest to classify the Plants of the Gods. Richard Evans Schultes revolutionized science and spawned another revolution he never imagined.

I haven’t watched the documentary yet but can’t quite see how LSD relates directly to Richard Evans Schultes. Of course he worked with Albert Hofmann, the discoverer of LSD, on several occasions but to the best of my knowledge all of Schultes’ work were based on botany and dealt with botanical compounds (some of which have properties similar to LSD, granted). I hope this angle is not “forced” upon the documentary in an attempt to draw in more viewers (I’m imagining arguments like “botany? arrrr that’s too boring - let’s throw in some LSD” ;-) ... but I guess I better watch the documentary before jumping to conclusions ;-) I’m also wondering about the wording: “the discovery of peyote” - peyote (Lophophora williamsii) use is documented back to prehistoric times so it doesn’t really make sense to award the honor of “discovering” peyote to anyone.

Information on the peyote cactus et cetera. The primary focus of the Lophophora Blog is small Mexican cactus species like Lophophora (peyote), Obregonia (artichoke cactus), Acharagma, Ariocarpus (living rock), and Strombocactus but occasionally other subjects will be dealt with as well. Welcome to the Lophoforum and happy growing :-)
